K12 export localinstall wampserver

Hi everybody,

I wanted to ping the group regarding "best practice" or advice on building a new site that will replace our current K12 District site. Do you think it is best to build it local on say a laptop using wampserver and then migrate it over to a host and how hard is this? Or....install it on a spare server I have in our server room using a temp domain name and then migrate it over to a host (again how difficult is the migration process). Looking for advice from all of you who I am sure have done this many times or at least once and what strategy you recommend. Thanks!!
